Within the improved quantum molecular dynamics (ImQMD) model incorporating the statistical decay model, the reactions of ${}^{238}\mathrm{U}+{}^{238}\mathrm{U}$ at an energy of $7.0A$ MeV have been studied. The charge, mass, and excitation energy distributions of primary fragments are investigated within the ImQMD model, and de-excitation processes of these primary fragments are described by a statistical decay model. The mass distribution of the final products in ${}^{238}\mathrm{U}+{}^{238}\mathrm{U}$ collisions is obtained and compared with the recently obtained experimental data.
